Alex made a sketch for a homeade soccer goal he plans to build. the goal will be in the shape of a triangular prism. the legs of the right triangles at the sides of his goal measure 4ft and 8ft, and the opening along the front is 24ft. how much space is contained within this goal

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

multiply then divide
